We use angle-resolved photoemission (ARPES) to study the three-dimensional (3D) electronic structure of Co pnictides $A{\mathrm{Co}}_{2}{\mathrm{As}}_{2}$ with $A=\text{Ba}$, Sr, Ca or a mixture of Sr and Ca. These compounds are isostructural to Fe based superconductors but have one more electron in the Co $3d$ orbita…
Abstract We report on the morphology and optical properties of CuInS 2 /ZnS core-shell quantum dots in solid films by means of AFM, SEM, HRTEM, steady state and time-resolved photoluminescence (PL) spectroscopy. The amount of aggregation of the CuInS 2 /ZnS QDs was controlled by changing the preparation conditions of…
The leaf extract of Strobilanthes flaccidifolius Nees. was used for the synthesis of silver nanoparticles through a green technique of synthesis. The nanoparticles was characterized by UV-VIS spectroscopy which proves the formation silver nanoparticles. FTIR (Fourier Transmission infra red spectroscopy) study was carr…
An accelerated corrosion test, known as proving ground accelerated test, is commonly performed by automotive manufacturers to evaluate the corrosion performance of a vehicle. The test combines corrosion and durability inputs to detect potential failures that may occur during in-service conditions. Currently, the test…
Single crystals of various types of diamonds have been grown by the melt solution crystallization at high pressures and temperatures. To define the emergences of dislocations onto the {100} and {111} faces, the selective etching of the crystals in KOH and KNO₃ melt has been used. It has been defined that the dislocati…
In the production and development of building materials, burned clays are the center of major interest, particularly in the building industry. Henceforth, in order to analyze the effect of heat treatment on illite-rich natural clay samples from Turkey samples were exposed to heat at various temperatures between 350-65…
In this letter, several converging fishnet metalenses are designed using both the zoning and reference phase techniques. They are engineered with a focal length of 1.5λ0at the design frequency of 55 GHz (λ0= 5.45 mm) at which the fishnet metamaterial has an effective refractive index of nlens= ~0.68. Three metalenses…
Based on the facts that most components and devices are based on silicon and modern industry is transferring to atomic scale era, engineering half-metallicity in low-dimensional silicon-based materials has vast importance in spintronic field, since such half-metals can perfectly match with the previous silicon-based c…
High Resolution Image Download MS PowerPoint Slide Long-term preservation of the properties of gold nanoparticles in both solution and the dry powder form can be difficult. We have overcome this challenge by using organotellurium derivatives as both reducing agents and stabilizers in the synthesis of gold nanoparticle…
Abstract In situ multiphase structure Gd 65 Mn 25 Si 10 alloys were fabricated by melt spinning and subsequent crystallization treatment. In the process of crystallization, the α -Gd, GdMn 2 and Gd 5 Si 3 phases precipitate in the amorphous matrix in turn. The Curie temperature ( T C ) values for the α -Gd crystalliza…
Abstract The triboluminescence of Eu 2 (SO 4 ) 3 ·8H 2 O and Tb 2 (SO 4 ) 3 ·8H 2 O crystals in an atmosphere of sulfur dioxide (SO 2 ) or sulfur hexafluoride (SF 6 ) was studied. Quenching of the gaseous (emitter N 2 ) and solid‐state (emitter Ln 3+ ) components of the triboluminescence (TL) emission spectrum was see…
, respectively. However, when Au is in a modest oxidation state of +1, the overall reaction barrier for the WGS reaction via the carboxyl mechanism is reduced to 0.79-0.98 eV. It therefore appears that Au species with an oxidation state of +1 play a significant role in the WGS reaction at low temperatures (T < ∼550 K).
Introduction. Height estimation from the remaining skeleton has a great importance for personal identification in forensic medicine and anthropometric studies. This study emphasized the height estimation from ulnar length in Chabahar population.<br/> Objective. One of the most important items in individual identificat…
Abstract Isotropic plasmonic clusters consisting of a controlled number of gold satellites around a silica core are fabricated from silica/polystyrene tetrapod, hexapod, and dodecapod templates. The synthetic pathway includes stages of site‐specific seed adsorption, seed‐mediated growth, and iterative etching/regrowth…
A solvent-assisted solid-to-solid polymorphic transition, which was assumed to be one of the key processes for the occurrence of preferential enrichment (PE), has been proven to occur by means of temperature-controlled video-microscopy (TCVM) and time-resolved in situ X-ray powder diffraction (XRPD) measurement during…
A challenging problem of modern surface-enhanced Raman spectroscopy (SERS) analysis is related to the design of new composite materials with bioprotective properties providing either a reproducible signal of small quantities or intactness of protein molecules. A new way of modification of silver-based SERS-active subs…
A surface-enhanced Raman scattering (SERS) system for the simple, sensitive and homogeneous detection of UDG activity based on silver nanorods (AgNRs) was developed.
H is influenced not only by the nitrogen content but also by the coordination of the heteroatom; substitutional nitrogen demonstrates a higher effect compared to pyrrolic and pyridine-like nitrogens.
The enhanced maleic anhydride-end-capped poly(propylene carbonate)/starch blends were prepared through starch oxidization and modification with a coupling agent, aluminic ester. The interfacial interaction, rheological behavior, and properties of blends were investigated through Fourier transform infrared spectroscopy…
Performing diverse application tests on synthesized metal oxides is critical for identifying suitable application areas based on the material performances. In the present study, Ni-oxide@TiO₂ core-shell materials were synthesized and applied to photocatalytic mixed dye (methyl orange + rhodamine + methylene blue) degr…
